SMS Marketing Consent via Transpond
In line with UK regulations, you must obtain consent from your contacts before engaging in SMS marketing. With Transpond, you can record consent for SMS marketing when collecting subscribers via your Signup Forms.
In addition to recording consent, it is considered good practice to detail the nature and frequency of SMS messages a contact can expect to receive, as well as a link to your privacy policy (if available).

How to record SMS Marketing Consent via a Signup Form
The first step is to create a custom field to record if a contact has given consent to SMS Marketing. To do this:
- Click Contacts in the top navigation bar of Transpond
- Choose All Contacts > Fields
- Click + Add a Field
-
Complete the field details:
- Give the field a meaningful name along the lines of SMS Opt-In or SMS Consent Given
- For the field type, select TRUE/FALSE
- Select + Add Custom Field to add the new field to Transpond.

Once the custom field has been created, you need to create a new signup form or edit an existing one.
- When viewing the edit form screen, from the Elements menu on the left, drag a new checkbox field onto the form in the preferred position.
- In the Content tab for the checkbox, under Field, select the TRUE/FALSE custom field you created in the steps above and then edit the label text.

- To add information on the nature and frequency of SMS messages a contact can expect to receive, drag a text field from the Elements menu on the left of the screen and enter the details.

In order to provide SMS marketing, Contacts will need to have a mobile phone number. If you aren't already collecting phone numbers via your signup form, you will need to add a field for this on the form too.
How do Contacts opt out of SMS Marketing?
On every SMS message you send via Transpond, an opt-out link will be automatically added.
If a contact decides they no longer wish to receive SMS marketing from your Organization, they can tap the link in the text, which will take them to a webpage. Here, they can enter their phone number to opt out.

SMS Marketing Quiet Hours
Within the UK, SMS marketing messages can be sent between 9 am and 8 pm. Outside this time is considered "Quiet Hours".
In order to be compliant, you must not send during quiet hours. Transpond helps you with this compliance by not allowing campaigns to be scheduled or started before 9 am or after 8 pm.

If you're using an SMS step within an Automation, the Automation will respect the quiet hours of 8 pm through 9 am by holding contacts at the step until quiet hours have passed. After this time, the SMS will be sent, and the Contact will continue through any additional steps in the Automation.
How to set the SMS Marketing 'From Name'
To set a default 'From Name' for your SMS Marketing in Transpond:
- Click on your profile image in the top right corner of the screen > Account Settings > then click the SMS tab.
- Here, you can enter your default name. This should clearly identify your organisation as the sender of the SMS messages. The name must be 3-11 characters long and have no spaces.

If you want to use a one-off name for a specific campaign or if you work with multiple brands/services, the default 'From Name' can be overridden when creating your campaigns.
